I too have the exact same problem!
with the old firmware everything was ok, now with version 3.0.1 the sonoff is online but you can't change the switch!
At me not solved. Basic is at 3.0.1, Ewelink at 3.6.1
It is possible to switch the basic via a scene from a T1-switch. It is possible to switch the basic via Google home and Alexa. But via ewelink I can do nothing.
I have same problem after upgrade 3.0.1.
Do you know how to fix this problem?
I want to know how to downgrade 3.0.0 if it is can't fix.
I have a lot of devices to update and have started upgrading to firmware 3.0.1
When I view my devices using the Ewelink app on my iPad Pro, I notice the LAN icon is displayed alongside the devices which have successfully updated whereas all the others (yet to be updated) have the WiFi icon alongside them
The upgraded devices appear to be working properly and can be controlled via the Ewelink app on the iPad or via Amazon Alexa.
Before upgrading the rest of my devices:
Does this firmware upgrade now force devices to connect via LAN instead WiFi as before?
Can anyone tell me what issues this upgrade addresses and/or what improvements it contains?
All devices including Basics, 4 CH Pro R2 and USB DC5V Relay Module successfully upgraded to firmware 3.0.1
and there is a Wi-Fi icon alongside each device in EweLink App.
Just got 3.0.1 on 2/3/4 gang devices. Interlock i like, but I need to use it together with inching. As an example for curtain control.
Since the upgrade to firmware 3.0.1, I'm having issues with some of my Sonoff RF (not all of them though).
One of the devices does not connect to my wifi anymore. I have to reset it every day.
Another one of my devices does not start in the morning as scheduled (it does turn off though).
p.s. my wifi is turned off every night and turned on every morning thanks to another Sonoff RF.
I did not have those issues with firmware 2.6.
it would be great to be able to downgrade easily.
I have https://www.itead.cc/inching-self-locking-wifi-wireless-switch.html and am having the same issues after upgrading the firmware to 3.0.1.
My ewelink app is on 3.7.0.
I have tried connecting the device to two different routers and am experiencing the same issue.
Removing the power source and reconnecting it doesn't work; the only thing that works is re-pairing the device but it will disconnect from the wifi 1-2 hours later.
Has anyone figured out a solution for this problem? I didn't backup my old firmware so I cannot revert.
